(2/9) * (8/9) = (2*8) / (9*9) = 16/81 and: 2/9*8/9 = 16/81 2/(9*8)/9 = 1/324 2/(9*8/9) = 1/4 it depends on where you put the brackets

2^9 = 512 9^2 = 81
2 + 2 + 9 = 13

2/9 + 2/3 = 2/9 + 6/9 = 8/9
Assuming that is not a sequence of numbers, but there are missing plus signs: 4 + 9 + 2 + 2 + 6 + 9 + 9 + 2 + 9 + 7 + 9 + 4 = 72
2/9 × 18 = (2×18)/9 = 36/9 = 4 Alternatively, cancelling as you go: 2/9 × 18 = (2×18)/9 = 2×(18/9) = 2×2 = 4

9*2 = 18
2/3 is same as 6/9..is 6/9 greater than 2/9?..yes it is..by 4/9
-9
two 1 / 9 x 9 = 1x9 / 9 = 9 / 9 = 1 / 1 = 1 2 / 9 x 9 = 2x9 / 9 = 18 / 9 = 2 / 1 = 2
3x+9/2=9 3x=9-9/2 3x=9/2 x=9/6 x=3/2
81. (9 to the power of 2 = 9 x 9).
